Abstract

Des modes de réalisation de la présente invention concernent un procédé, un appareil, et un système pour la détermination de ressources de rétroaction HARQ, aptes à résoudre le problème de configuration de ressources de rétroaction HARQ par une extrémité d'envoi pour une extrémité de réception. Le procédé comprend les étapes suivantes : d'après des informations de capacité de traitement d'une extrémité de réception et/ou la priorité de données transmises entre une extrémité d'envoi et l'extrémité de réception, l'extrémité d'envoi détermine des ressources de rétroaction HARQ de l'extrémité de réception, les ressources de rétroaction HARQ de l'extrémité de réception étant utilisées pour transporter des informations HARQ correspondant aux données transmises entre l'extrémité d'envoi et l'extrémité de réception ; et l'extrémité d'envoi envoie des informations d'indication à l'extrémité de réception, les informations d'indication étant utilisées pour indiquer les ressources de rétroaction HARQ de l'extrémité de réception.
